[PATCH v1 0/3] Remove the limitation of Intel PT CPUID info

2020-02-24 Thread Luwei Kang
The Intel PT feature includes some sub-features(CPUID.(EAX=14H,ECX=0H)) and these sub-features are different on different HW platforms. To make the live migration safety(get the same CPUID info with same cpu model on different HW platform), the current Intel PT CPUID information is set to a
